SPECIFICATION forming part of Letters Patent No. 611,287, datedSeptember 27, 1898.

Application filed December 81, 1897. Serial No. 665,194.. (No model.)Patented in Germany October 8, 1895, No. 88,381, and in Austria November30, 1897, No. 47/511313.

To all whom it may concern:

Be it known that I, LAZAR MLADEN SERBAN, a subject of the Emperor ofAustria-Hungary, residing in the city of Vienna, in the Province ofLower Austria, in the Empire of Austria- I-Iungary, have inventedcertain'new and useful Improvements in Changeable Toes for Horseshoes,(for which I have obtained a patent in Germany, No. 88,381, datedOctober 8, 1895, and in Austria, No. 47/5,133,'dated November 30, 1897,)of which the following is a specification.

This invention has reference to improvements in horseshoes, and moreparticularly to changeable'toes for horseshoes and their connectingdevices.

It is the special object of this invention to insure a quick andreliable attaching and removal of the toe.

The toe is securely fixed to the horseshoe by means of a peculiarattachment consisting in a securing-screw and laps which embrace thehorseshoe.

The invention is illustrated in theaccompanying drawings.

Similar letters of reference denote like parts in all of the drawings.

In the drawings, Figure 1 is a bottom view of the toe part of a completehorseshoe attached to a hoof; Fig. 2, a vertical section of Fig. 1. Fig.3 is a top plan view through the fore part of the horseshoe with aconically downward converging slot for the connecting-screw. Fig. 4 isan inside view, and Fig. 5 is a vertical section. Figs. 6, 7, and 8illustrate a modification with semicircular conical slot and bridge,Fig. 6 being an oblique view, Fig. 7 an inside view, and Fig. 8 asection. Figs. 9, 10, and 11 show another modification withsecuring-bar, Fig. 9 being a plan view, Fig. 10 an inside view,and Fig.11 a crosssection. Fig. 12 illustrates the manner of inserting theconnecting-bolt into ahorseshoe on the hoof, Fig. 13 represents ascrew-bolt with truncated pyramidal head. Fig. 1 1 shows a screw-boltwith semicircular truncated conical head and supporting-laps. Fig. 15shows a screw-bolt with laps only. Fig. 16 is a perspective View of atoe with full lap in front known manner, is enlarged on the fore bentpart and is provided at the bent part toward the heel with a recess 1),into which recess the head al of the toe-screw d may be inserted. Thisrecess b may be shaped either conically downward diverging'or prismatic,with parallel sides, or it may be cylindrical or semicylindrical.

Figs. 3 to 5 illustrate a horseshoe with pyramidal slot, Figs. 6 to 8with a semicircular slot, and Figs. 9 to 11 with a somewhat differentsemicircular slot for the toe-screw. In order to partly relieve thescrew-head al the slot may be provided with a projection or stay 1),,upon which may rest a corresponding lap or projection d of the head ofthe screw, Figs. 2, 8, and 11.

Prismatic or cylindrical heads, Fig. 15, are used solely for supportingthe screw-bolt on the projection 12,, extending flange-like on threesides. The screw-bolt, Figs. 13 and 15, whose head is inserted into slotb, extends outward with its threaded part d passing through a hole f, inplate f which carries the toe and receives there a screwed-011 nut g,which secures the toe to the horseshoe, as shown in Figs. 1 and 2.

The toe consists (see Figs. 16 to 20) of the toe-body proper, f, and ofthe angle-plate f which rests on the bottom side of the horseshoe andembraces the latter by means of one or two laps h 71 These laps may bemade of one continuous piece, as shown in Figs. 16 to 18, or they may bedivided in flaps, as shown in Figs. 19 and 20. One only-for instance, h,

may be located on the external bend or protuberance, Fig. 17, or one, 71may be on the internal one, Fig. 17, or both, h 77. may be applied, asis shown in Figs. 19 and 20. The laps h 72 may also be constructed insuch a manner that they are directed outwardly when the toe isunmounted, Fig. 20, and when the toe is pressed against the horseshoethen the laps are pressed against the wall of the same, as shown in thedotted lines in Fig. 20.

The connection of the toe is effected in a simple manner by laying orputting at first the screw (Z, with its head d laterally into the slot1), Fig. 12, whereupon the toef, with its plate f is put upon the bolt dand secured by screwing 011 the nut g. The removal of the toe f whenused up is effected in the reverse manner. The laps h h extending upwardover the edge of the horseshoe, have the purpose to fix first the toesecurely to the shoe and to take up shocks, strain, &c., and thus torelieve the screw.

In order to protect the nut g against damage, ribs 712 may be providedon the lower side of the toe-plate f alongside of its side walls, theend of the ribs being a little swelled at 70 to strengthen them. Theseribs project beyond the nut g and are worn out uniformly with the toeand protect the nut g, preventiug it from quickly wearing out.

Having thus described my invention, I claim 1. A horseshoe with enlargedfore-bent portion provided at the bend with a slot, a screwbolt fittingin the slot, a changeable toe composed of the toe-body proper, anangle-plate with opening for the screw-bolt and resting on the lowerside of the horseshoe and embracing the same by laps, and asecuring-nut, as specified.

2. A horseshoe with enlarged fore-bent portion provided at the bend witha pyramidal slot, a screw-bolt with a truncated pyramidal head fittingin the slot, a changeable toe composed of the toe-body proper, anangle-plate with opening for the screw-bolt and resting on the lowerside of the horseshoe and embracing the same by divided laps, asecuringnut, and nut-protecting ribs on the toe, as specified.

3. In combination with a horseshoe having a fore-bent portion with apyramidal slot, a changeable toe composed of the toe body proper carriedby a plate provided with divided laps and an opening, a screw-bolt witha truncated pyramidal head fitting into the slot and passing through theopening in the plate, a securing-nut, and nut-protecting ribs withenlarged heads on the toe, as specified.

In testimony whereof I have signed this specification in presence of twosubscribing witnesses.
